1/1/2011 - Peer reviewed journal articlesThis paper examines the EMG responses of knee extensors/flexors to lifting in kneeling or squatting postures and discusses the impact of posture and kneepads on muscle recruitment and explores the implications for work in such postures.
-
9/1/2010 - Conference papersThis study assessed the difference between free cadence walking versus stoopwalking (under a 1.2-m ceiling), four-point crawling (hands and knees), and two-point crawling (knees only), both with and without kneepads.
-
8/1/2010 - Conference papersNIOSH investigated muscle activity, forces, stresses, and moments at the knee (with and without kneepads) while subjects assumed various postures, including kneeling in full flexion, kneeling at 90° of flexion, kneeling on one knee, and squatting.
-
2/1/2010 - Information CircularsThis report describes a study of operator movement relative to the motion of a roof bolting machine boom arm. This work was aimed at reducing the risk of injury to underground coal mine workers from moving machinery.
-
10/1/2009 - Conference papersBy surveying experienced equipment operators about visual cues, researchers developed a method to gather data on the needs and practices of machine operators while controlling the machine and the reasons for needing particular operational cues.
-
8/1/2009 - Conference papersThe pressure applied to the patella and combined PT and TT was determined for postures associated with low-seam mining.
-
8/1/2009 - Conference papersIn this study thigh-calf and heel-gluteus contact forces were quantified to on the externally applied flexion moment in high flexion.
-
12/1/2007 - Peer reviewed journal articlesThis article discusses research results of studies that shed light on possible mechanisms through which low back injuries may occur and how this knowledge can be leveraged to reduce the risk of low back pain.
-
8/1/2007 - Peer reviewed journal articlesIn this study, survival analysis techniques were used to compare fatigue failure responses of elderly motion segments to a middle-aged sample. This study also evaluates the influence of bone mineral content on cycles to failure.
-
12/1/2006 - Technology NewsDiscusses a first-generation mobile manipulator that one person can use to lift and maneuver 50- to 600-pound loads. It can be used in maintenance shops and mines to reduce lifting accidents.
